Tissue engineering relies on four important factors: the right cells, the right scaffold environment to support cell growth, the right biomolecules like growth factors, and physical and chemical processes. Tissue engineering is used to replace damaged or diseased tissues through a process of harvesting cells, using a scaffold structure for cell support and growth, and placing the cells in the right environment for nourishment. Common tissues engineered include skin, muscle, and bone, while entire organs like the heart and kidney may also be regenerated through this process. The first approved product was an artificial skin used for burn victims.
Applications of biotechnology

- 2. Biotechnology and its common uses... • It is the industrial use of biological processes from microorganism to make substances or to provide services
- 3. Tissue Engineering • Tissue engineering is the use of combinations of cells, different material methods, and bio and physiochemical processes to improve or replace biological tissues • It is the replacement of damaged or diseased tissues • Its purpose is to maintain or improve damaged tissues or whole organ • The first such product to gain approval for clinical use was a form of artificial skin consisting of a thin sheet of collagen gel infiltrated with two layers of cultured human cells.
- 4. Factors tissue engineering relies upon… • Tissue engineering relies on 4 important factors: Right cells to do the job Right environment such as scaffold to support the cells Right biomolecules like growth factors to make the cells healthy and productive Physical and chemical process to influence the development of the cells
- 5. • Cells are important for tissue engineering because cells collide to make up a tissue and then they carry out the function • Tissues that are mostly required are Skin Muscle Bone • Regeneration of entire organ is too possible Heart Kidney Liver
- 6. Process • To harvest cells directly from the target organ • Need a structure for support that is the scaffold it comes in different sizes • Gives a structure to cells for their better growth • Human stem cells are mostly used, they can be used to make any tissue of the body • Putting cells in the write environment is crucial for the proper nourishment and growth
- 8. In vitro meat • Cultured meat, also called , cell- cultured meat, and in vitro meat, is meat grown in cell culture instead of inside animals. Cultured meat is produced using many of the same tissue engineering techniques traditionally used in regenerative medicine. Cultured meat has not yet been commercialized due to some technical challenges. The first cultured beef burger patty was created by Dr. Mark Post and was eaten at a demonstration for the press in London.
- 9. Artificial Organs • Artificial organs are classed into four groups: Bone or joint replacement (knee, finger or hip bones) Skin or soft tissue replacement (skin, muscle) Internal organs (heart, kidney, liver, pancreas) Sensory organs (eye, ear)
